IMPROVEMENT 1N PRoPAGATrNG-oxron PLANTS.

lLlEheSChedule referred to in these Letters Patent and making part ofthe same.

Know all men by these presents:

That I, CLARK J1LLSON,'of the city and county of Worcester, andCommonwealth of Massachusetts, have invented certain new and usefulImprovements in Propagating-Boxes; andI do hereby declare that 'thefollowing is a' full, clear, andexact description of thesame,

reference being had to the accompanying drawings,

forminga part of this specification, in which Figure -l represents aperspective view of my improved propagating-box, as it appears when inuse;

.Figure 2 representsa top .or plan View of the box before the straw andearth have been placed therein; and

Figure 3 represents a longitudinal central section of the box andcontents shown in g. 1.

To enable those skilled: in the art to which my in,

vention belongs, to make and use the same, I will give a more detaileddescription thereof.

'Ihe nature of my invention consists- First, in the combination, withthe plant-box, of a solar-heat-retaining box, iilled with stones, or theequivalents thereof', as hereafter explained.

Second, in such an arrangement of parts as to insui-ea constantpermeation-of the' earth and roots of the plants by air heated by solarheat, as hereafter explained. Y

Third, in the combination, with the plant-box and solar-heat-retainingbox, of the slatted or open earthrack, as hereafter explained.

Fourth, in a plant-propagating box, the parts -ofV which are constructedand arranged i'n relation to ea'ch other, as and for theapurposeshereafter explained.

In the drawings- A is the plant-propagating box;

B, the solar-heat-retaining box; and

' C, the slatted earth and plant-supporting frame.

Y Frame C rests'upon the pieces ma., fastened to the inner sides of theplant-box, and it is also provided with vhails b b, by means ofwhichitean beeasilyl liited out, for the purpose ofitransplanting the youngandrgrowing plants. Y

The space D, under l the slatted frame C, serves as an air-chamber. i

The tops of the boxes A and B are provided with sliding or other glasscovers d, while the outer end of theebox'B is 'provided with airholes e,and the front upper endl'of the box A is perforated with"holes'f, whichserve for ventilation 'as' well as `for the ingress of water, which Inaybeturned into the waterbox-E,

grow.

The box B is to be filled with stones H, or some othersolar-heat-retaining substance. I prefer to paint the stones black.

It may-be well to-.placea straw covering over the I slatted flame beforeputting in the earth.

The operation is as follows:

The boxes being filled and the legs I turned down,

so as to elevate and support the boxes in the inclined position as shownin iig. 1, the heat fromthe sun is. concentrated by the glass coversupon the'earth and growing plants i'n`the box-A, and upon the stones Hin the box B. l

"The heated air in the box B passes into the airchamber D; thence upthrough the slatted frame C, straw g, and'earth F, and out of the holesf, thereby keeping the' roots constantly `warm and the plants in athrifty and growing condition. DuringA the daytime, the stones becomehighly heated, and consequently the. heat therefrom isv given out orgradually passes oi during the night, and warms the air, which is inconsequence vkept in circulation through theearth androots of the plantsduring the night; as well as the day.'

Having describedv my improved propagating-box, W'hat I claim therein asnew and of my inventipn, and desire to secure by Letters Patent,is-f- 1. The' combination, with the plant-box, of asolar--heat-retaining box, partially filled with stones, o r thev4 equivalentthereof, substantially as and for the pur-t poses set forth.

2.- The arrangement ofthe'perforated schr-heatretaining box, `perforatedplant-box, and slatted yearthsuppoiting frame, substantially as' setforth, whereby a constant circulation of heatedair is kept up, as andfor the purposes described.

3. The combination, with the plantbox, constructed asidescribed, ofthedoublebailedslatted earth-frame C, substantially'as and forthe purposesdescribed.

.4. A plant-propagating box,- composed of the plantbox A,solar-heat-'retainiug box B, slatted earth-frame C, supportinglegs I,and'waterfbox E, said parts being constructed and arranged in relationto each other, substantially as and forthe purposes set forth. v CLARKJILLSON.
